For Developers

OpenAI-compatible. Every model.

Point your existing OpenAI SDK at https://llm.smoo.ai/v1 and ship. Your virtual key is the only thing that changes.

Quickstart

Sign up, create a virtual key from your dashboard, drop it in. Same SDKs, same shapes — just a different base URL.

curl
curl https://llm.smoo.ai/v1/chat/completions \
  -H "Authorization: Bearer $SMOOAI_LLM_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "claude-haiku-4-5",
    "messages": [{"role": "user", "content": "ping"}]
  }'
python
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["SMOOAI_LLM_KEY"],
    base_url="https://llm.smoo.ai/v1",
)

resp = client.chat.completions.create(
    model="claude-haiku-4-5",
    messages=[{"role": "user", "content": "ping"}],
)
print(resp.choices[0].message.content)
typescript
import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.SMOOAI_LLM_KEY,
  baseURL: 'https://llm.smoo.ai/v1',
});

const resp = await client.chat.completions.create({
  model: 'claude-haiku-4-5',
  messages: [{ role: 'user', content: 'ping' }],
});
console.log(resp.choices[0].message.content);

Why it's smoother than DIY

Every frontier model

OpenAI, Anthropic, Google Gemini, Groq, plus direct DeepSeek, Alibaba DashScope (Qwen), Moonshot (Kimi), Z.AI (GLM), and MiniMax — at lab list prices, no aggregator markup. ElevenLabs for voice. 100+ model routes today.

Zero proxy overhead

Direct calls to the gateway. No Lambda cold start, no smooai middleware in the path. Same LiteLLM auth + rate limit you would self-host.

Built-in playground

Test prompts in /chat_ui without writing code. SSO from your smooai login — same workspace, no separate auth.

Drop-in compatibility

OpenAI SDK, LangChain, LlamaIndex, Vercel AI SDK — anything that takes a base URL works unchanged.

Live API docs

Full Swagger UI + OpenAPI spec at /docs. Auto-generated client types for every supported model.

Streaming, tool use, JSON mode

Everything the upstream model supports works through the gateway. Pass-through for kwargs the OpenAI shape does not cover.
